The rest of the side remains as it was named for the opening round against the Reds at Canberra Stadium.

Brumbies Captain Ben Mowen said the Force was always a difficult team to beat, particularly when facing it in the west.

"Over the last two or three years some of the toughest battles we've faced have been against the Force, particularly when we are playing them here in Perth," Mowen said.

"There was no better example of that than the last round of last year when they managed to knock us off quite convincingly.

"After a disappointing start to the season last week, we know what areas need to improve. If we can achieve those changes then there's no reason we can't come home with our first win of 2014."

Since 2011, the ledger is almost even between the two sides with the Brumbies winning three matches, the Force two and one draw.

The Force will field up to nine former Brumbies Academy or Brumbies players in their team on Saturday, with Robbie Abel, Phoenix Battye, Nathan Charles, Adam Coleman, Zack Holmes, Ian Prior, Junior Rasolea, Ed Stubbs and Rory Walton all currently holding contracts in the west.
